ABERDEEN, UK — Well-Safe Solutions has added a D300 saturation diving system to the semisubmersible P&A Well-Safe Guardian rig.
The customized spread, with capacity for up to 15 people, provides access to subsea wellhead and christmas tree systems from the 1970s onward that were originally designed for diver intervention.
Well-Safe Solutions CEO Phil Milton said, “The dive spread system installed on the Well-Safe Guardian is a cost-effective, flexible alternative to the industry standard, which typically sees a light well intervention vessel [LWIV] used to plug and lubricate the well before completing decommissioning operations with a standard semisubmersible mobile offshore drilling unit [MODU]. Our single asset solution offers an alternative to the conventional approach and does not require multiple vessel mobilizations and demobilizations. This results in lower operating costs, minimizes the risk of weather-related disruption and boosts overall project efficiency.”
Milton claimed that using Well-Safe Guardian to P&A five wells across three fields in the North Sea “generates a 15% total cost reduction and is 44 days quicker than using a LWIV and MODU pairing.”
The dive spread was manufactured, transported and fitted at the ports of Burntisland, Rosyth and Methil on the Scotland’s east coast. It includes an electric bell-handling system and two hyperbaric lifeboats.
Typical support operations are cleaning, deconstruction, barrier testing, manual tree cap removal, reconfiguration of hydraulic controls and flowline removal.
